============
syntax: (relations-of <frame-specifier>
{[:PART T | NIL | Var]
[:GENERAL T | NIL | Var]}+
[:DIRECT T | NIL | Var]

Warning: :PART and :GENERAL may both be set at a time.

This function returns the names of all characteristics
and/or parts of a frame as a list. If you only want
the characteristics of a frame, then you have to set
':GENERAL' to T. If you only want the parts of a frame,
then you have to set ':PART' to T. If you set ':DIRECT'
to T you only get all directly specified characteris-
tics and/or parts of a frame.
